The 2011 Vauxhall Insignia's first-time pass rate of 78.3% sits just below the UK average of 80%, which is a modest concern—but the real red flag is that 44.1% of these vehicles have had a dangerous defect flagged at some point, well above what you'd want to see. Diesel and petrol variants perform almost identically (78.4% vs 77.8%), so fuel choice won't solve the reliability question here.
These cars are averaging around 85,400 miles for their age, which is typical, but they're accumulating an average of 2.88 failures and 16.9 advisories per MOT cycle—suggesting wear items and minor faults are mounting steadily. Before buying, have a pre-purchase inspection focus on brakes, suspension, and cooling systems, since those represent the bulk of repeat failures on this generation.
The 2011 Vauxhall Insignia has a decent first-time pass rate (78.3%), but a higher-than-average share of vehicles have had serious defects recorded — the individual vehicle's history matters a lot here.
These stats describe 42,873 vehicles as a group. The specific vehicle you're looking at could be the one good example or the one outlier. Run its registration to find out.
